STORM WIN DOW ie'RQr-B- Ba alhyhia Ol ie Application November 26, 1945, Serial No. 630,796 1 This invention pertains to buildin structures, and more particularly to window closures or supplemental weather sash, generally known as storm sash, which are adapted to-be. temporari 1y installed for winter use and-subsequently re-:''

moved in the spring, or interchanged for summer; screen sash.

The object of the invention is to improve. the construction as well as the: means and mode of installation of such windows, whereby they may not only be economically manufactured and easily installed and removed, butwill be more. efficient in use, moisture and air tight, ofv sturdy constructionand not likely to-get out of: repair.

A further object of the invention is. to provide air and moisture tight joints for such temporary supplemental sash which will not become swollen when wet and-so tightlylocked in position as to resist removal.

A further object of the invention is to proznims. (c1.- .zoe-rn the permanentw-indow. The storm sash c. 1 prises an outer master frame I, which isfitted to and. permanently.- installed in the window opening, where duringsummerit may receive and support a screen sash of like. construction in alternation with the. glazed removable storm" stalled mastersash I' are formed with double spaced beveled contact faces 5 and 6, between which is a flatland' or face 1 parallel with the general plane .of the sash. At its top the master sash I is provided with a horizontal top rail 8,

having a groove 9 in its lower margin to. receive a matching-tongue Ill. upon the top margin of the upper V removable sash section 2. This tongue and groove joint is preferably, but not necessarily, o-i semi-circular cross section. A similar semi-circular horizontal tongue and groovejoint vide improved attachment means for securing the removable sash in place, and to provide an improved formof ventilator therefor.

With the above primary and other incidental objects in view as will more fully appearin the specification, the invention intended to-ube protected by Letters Patent consists of. the features of construction, the parts. and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or. illus.

trated in the accompanyingdrawings.

Referring to the drawings, wherein: is illustrated the preferred but obviously not necessarily the only form of embodiment of the invention,

Fig. 1 is a rear elevation of an assembled win-.

socket or bushing to be embedded in themo1int ing frame for engagement of an attachment screw.-

Fig. 5 is an elevation of an adjustable ventilator slide.

Like parts; are, indicated by similar characters of reference throughout the. several views,

,The present supplemental or stormfls ash is intended to be temporarily installedout'side a conventional Window with its transparent glass panes in parallel spaced relation with those of lI- -isprovided between the upper and lower removable sash sections 2 and 3. The side margins of both the upper and lower removable sash sec- {tions 2 and Sand the bottom rail of the lower section 3' are provided with double bevel contact surfaces 5 and 6' with an intermediate fiat face "V matching the corresponding contact faces of h aster frame I.

The intermediate flat faces I- and 1' of the sash sections 2 and 3 and'the frame I are normally spaced slightly apart to afford ample clearance space 1' to enable the beveled faces to be drawn more tightly together Wedgingengagement. This assures moisture and ai'rtight engagement of the matching beva e, not ike y t swell nd-s ck w t i e b s -or the permanentmaster, frame. 1,. .Hence. the

sash se tio s. 2 and 3 e re i y mov bl under a ev r condit on may P Q l t sections, 2 and 3- in the r ad s ed at w h thererma en r mast f ame. at a hme screws. F2" are r ded. at e ly spac d inte T nreven mut l iqn f the m st r fram yjrenetlt nus insertion and emoyal of wood screws, internally "screw threaded bushings [3 are embedded in the frame I at the selected positions for the attachment screws. Such anchor bushings I3 comprise peripherally corrugated bodies to lock the inserts against rotation. To further secure the anchor inserts I3 against displacement, one or more brads or nails I6 may be driven diagonally into the master frame into, thrust engagement with the corrugations of the inserts To afiord temporary ventilation the master frame I is provided with an opening I! at'any convenient point, which is exteriorly overlaid by a closure slide I8 having therein a large opening or a group of small openings I9 which may be "brought into registry with the sash frame opening 11 to admit air. The ventilating. opening I! j may be closed by shifting the slide I8.

closure is provided with angular slots I9, through The slide which extend guide screws 20, relative to which the closure slide may be elevated in an upwardly I diagonal direction and then permitted to descend by gravity in an opposite diagonal direction, I where it is held by gravity in alternately open and closed positions.

f It is 'to'beunderstood that the present window sash is designed to be removed from its mounting into the interior of the building structure. Wherefore, Fig. 1 is an elevational view of the inner side of the assembly and from the left of Fig. 2.

The marginal rabbet Id of the master frame I, as shown on the top and side frame members in -1 Fig. 1, is adapted to fit within and slightly overlap the margin of the top and sides of the original .window frame of a wooden structure or the corof a brick, stucco, or concrete structure.

responding parts forming the window opening While, as before mentioned, the sash members 2 and 3,

' whether of the storm variety or summer screens, are preferably removable inwardly from the master frame or mount I, the assembly may be 7 removed toward the exterior without departure from the principle involved or the scope of the invention.

'While throughout the specification and in the following claims reference is made to the assembly as a window closure and window sash,

it is to be understood that the invention is not restricted thereto, but is equally applicable to door openings wherein the assembly forming the subject matter hereof may be utilized as a convertible storm door'for winter use and a screen door for summer use. Consequently, the terms window structure and storm window and fstorm sash herein employed shall be interpreted generically to include also doors of .both

storm and screen type within the scope of the accompanying claims.

From the above description it will b'e apparent f that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but

which obviously is susceptible of modification in its form, proportions, detail construction and j arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.

Having thus described my invention, I claim:

1,. A supplemental temporary storm window, wherein a master frame is permanently secured in a window opening in parallel spaced relation with the normal window sash thereof, with which upper and lower sash sections are detachably engageable, characterized by horizontal tongue and groove joints between the detachable upper and lower sash sections, and between the upper sash section and the top rail of the master frame, double beveled joints between the vertical side margins and bottom margin of the lowermost of the detachable sashes and the interior vertical side and bottom margins of the permanently mounted master sash, comprising parallel laterallyoffset beveled contact faces on the respective sashes and frame and fiat parallel faces intermediate the beveled contact faces of the frame and respective sashes in parallel relatlvely spaced relation with each other, affording intermediate clearance for wedging adjustment of the opposed beveled contact faces, machine screws for attaching the detachable sashes to the master sash, and anchor inserts having screw threaded bores embedded in the master sash receiving the ends of the machine screws when thrust through the removable sash.

2. A window structure wherein a divided sash member is detachably engageable with a supporting frame, including substantially semicircular tongue and groove joints between the divisible sections of the sash member and between I the top of the divisible sash member and the top of the frame, and beveled interengaging marginal contact faces between the vertical sides and bottom of the sash and frame, and pressure means for drawing the sash into tight wedging engagement of the beveled contact faces of the sash with those of the frame.
